Aw, darn. I thought this was a job for The Dialectizer, but it doesn't do Yiddish. Here's how it thinks Elmer Fudd would do it:

BANKS OF DE OHIO
I asked my wove to go wif me,
Just to wawk a wittwe way.
And as we wawked, 'twas then we tawked
Of ouw appwoaching wedding day.

cho: Den onwy say that you'ww be mine
And in no othew awms entwine.
Down beside, whewe the watews fwow
Down by the banks of the Ohio.
